Resumo

The genetic variation in traits of growth and shape and their distribution among and within ten Australian provenances of Araucaria cunninghamii was studied under the environmental conditions of Luiz Antonio, state of Sao Paulo. The provenance test was implanted in 1985 with six replications and row plots of four plants each. The F test of the analysis of variance showed significant differences at 1% probability among provenances for height and DBH at 20 years old. Of the total variation in height, DBH and trunk shape, variation among provenances accounted for 14.59%, 23.01% and 2.04%, respectively, after 20 years. At the same tree age, provenance Langkelly Creek performed best for traits DBH and height and Imbil Seed Orchard for trunk shape, while Bulburin performed worst for height and trunk shape and Jimna for DBH.
